IV.
Impedance measurement instruments can be classified as DC impedance and AC
impedance types.
A general multimeter can be used to measure DC impedance,
while a bridging instrument (such as this) can be used to measure AC or DC impedance.
The 72-10465 is an intelligent double-display portable LCR digital electric bridge,
with DC & AC impedance measurement functions. Impedance is one of the most
fundamental parameters to
analyze electronic elements and circuits. The resistance
of linear diode is defined by Ohm's Law as part of a DC power scenario. Ratio of
voltage and current is a complex impedance as part of an AC power scenario. One
impedance vector includes one real part (resistance R) and one imaginary part
(reactance X). Impedance is expressed by R+jX in a rectangular coordinate, or
expressed by the amplitude of real Z and phase angle of 0 in a polar coordinate
system. See figure 1-1 for relationship.
